Overseas companies in the UK: registration and filing obligations

Registration and filing obligations of an overseas company that opens an establishment in the UK.



This guide explains:

  • how to register an overseas company that opens an establishment in the UK
  • disclosure obligations subsequent to such a registration
  • documents you must send to Companies House
  • important rules on accounting requirements, company names and trading disclosures

It will be helpful if you’re:

  • an overseas company thinking of opening a UK establishment
  • an overseas company with a UK establishment looking for basic guidance on your continuing filing and disclosure obligations
  • acting as an adviser to an overseas company and are looking for guidance on registration and disclosure requirements in the UK

The UK is no longer part of the EEA. Companies with a registered UK establishment and whose ‘home’ country is inside the EEA, must now report the same information as overseas companies.
